I -2 claims; (c1. 2i-79) This `invention relates .to garment fastenersand more particularly to a buckle for use in association with an overallshoulder strap for detachably locking said strap tightly thereto.

One :object of 'the invention is to provide an improved overall buckleof the above nature which may be releasably and adjustably locked to theshoulder strap by means of a swinging angle-shaped toggle cross bar.

Another object is to provide an improved overall tight-locking buckle ofthe above nature having a pair of opposed transverse outwardly curvedtongues at its lower end to facilitate the attachment to and removal ofthe buckle from the overall button.

A further object is to provide a device of the above nature which willbe simple in construction, easy to manufacture, easy to install andmanipulate, compact, ornamental in appearance and very eflicient anddurable in use.

With these and other objects in view there has been illustrated on theaccompanying drawing one form in which the invention may be convenientlyembodied in practice.

In the drawing:

Figure 1 represents a front plan View of a buckle embodying the featuresand principles of this invention.

Figure 2 is a rear plan view similar to Figure 1 in which the angle baris shown in locked position.

Figure 3 is a front plan view, similar to Figure 1, showing the buckleand portions of the overall shoulder strap and the overall garment,which is attached to said buckle by a button.

Figure 4 is a longitudinal sectional view of the same, the section beingtaken on the line 4--4 of Figure 3 looking in the direction of thearrows.

Figure 5 is a transverse sectional view taken on the line 5-5 of Figure3 looking in the direction of the arrows. l

Referring now to the drawing in which like reference numerals denotecorresponding parts throughout the several views, the numeral I0indicates a buckle frame which is provided with a straight top edge IIand a pair of side edges I2 and I3 which have straight upper portionsand convex bottom portions I4 and I5. The buckle II) is also vprovidedwith a substantially flat bottom edge I6 having a central dependingconvex section I1.

In order to permit the insertion of a shoulder strap 36 through thelower part of the buckle frame, provision is made of a transverseopening I8 into which extends, from the bottom portion ofside sections|4Jand I5, a pair of tongues I9 and 20 having their inner extremities,2I, and 22'spaced apart and curled out of the plane of said frame asclearly shown in the drawing. Y

By means otthis constructionpthe attaching neck 39 of a button 38secured to an overall garment 31 may readily be passed downwardlybetween the tongues I9 and 20 with a snap action to permit said neck 39to engage in a semi-circular central recess 23 located in the upper edgeof the convex central section I1 and with the button lying in front ofsaid tongues I9 and 20.

Surrounding the buckle frame at a point just inside the peripherythereof is a raised stillening rib 24 pressed in the metal, providing acontinuous groove 25 on the rear of said buckle body frame I0.

In order to permit the buckle to be detachably locked on the shoulderstrap 36 of the overall in any desired adjusted position along thelength thereof, provision is made of a pair of parallel rearwardly bentears 26 and 21 located at the top of the body frame I0.

The ears 26 and 21 are provided with apertures 26a and 21a for receivingthe reduced end pins 26h, 21h respectively of an angle shaped togglecrossbar 28 which is adapted to be freely pivoted in said apertures 26aand 21a (see Figure 5).

The toggle cross bar 28 is provided with a relatively wide flatintermediate section 29 which is adapted to extend parallel to thebuckle body frame I0 when in locked position shown in Figures 2 and 4,and perpendicular to said buckle frame I0 when in unlocked positionrespectively.

The intermediate section 29 of the crossbar 28 is provided with acentral concave recess 30 adapted to lie substantially parallel with acurved section I8a of the opening I8 in the body of the buckle when inlocked position. The section 29 is held in such raised position by apair of inclined curved tongues 3I and 32 at the side extremitiesthereof which engage the shoulder strap when the crossbar is locked.

The toggle crossbar 28 is provided at its rear end with a short lockingsection 33 located substantially at right angles to the intermediatesection 29 and said locking section 33 is provided with two alinedspaced rows of teeth 34 and 35, which are adapted to engage the fabricof the shoulder strap 36 with a snap toggle action at a point directlyin alinement with the groove 25 on the rear surface of the frame I0.

By means of this construction it will be seen that the crossbar may bereadily released by inserting one nger of the user in the recess 30behind the intermediate section 29, and swinging said crossbaroutwardly.

The button 38 previously mentioned is preferably secured to the fabricof the overall garment 31 near the top thereof by means of a pair ofspaced clamping disks 40 secured to the neck 39 and embracing saidfabric.

While there has ybeen disclosed in this specification one form in whichthe invention may be embodied, it is to be understood that this form isshown for the purpose of illustration only, and that the invention isnot to be limited to the specic disclosure, but may be modied andembodied in various other forms without departing from its spirit. Inshort, the invention includes all the modications and embodiments comingwithin the scope of the following claims.

Having thus fully described the invention, what is claimed as new andfor which it is densired to secure Letters Patent is:

1. In a buckle, a substantially rectangular frame having a transverseopening therein, and a straight upper edge, a narrow groove extendingbelow the surface of said frame adjacent said upper edge, a pair ofapertured ears upstanding from the plane of said frame at the oppositesides thereof adjacent said upper edge, a toggle crossbar having a pairof pins on the extremities thereof pivotally mounted in the apertures ofsaid ears to permit said crossbar to swing with respect to said buckleframe, said crossbar having an upstanding short locking'section at itsupper end which lies at right angles to the plane of said buckle frameand in alinement with said groove when said crossbar is in lockedposition 'whereby it will forceably press a shoulder strap in kinkedcondition into said groove with a strong toggle action, the width ofsaid narrow groove being substantially the same as the thickness of saids hort locking section. 5

2. The buckle as defined in claim 1 in which said crossbar has a pair ofinclined tongues for engaging said shoulder strap when in lockedcondition and providing a raised recess therebetween to permit thecrossbar to be swung open by the insertion of the users lingerthereunder.
